Week 5, Question 1: Using the force method, calculate the bending moment at D for this one-fold statically indeterminate frame. Ignore the axial and shear deformations and consider EI constant for the whole frame. Please use the gradual solution below and release M₁ as the redundant moment. Take a = 17 kN and L = 2.5 m. 3 m B ــــــ -2 m kN m kN m C D Part 3) Calculate the real bending moment at D MD = kN m * a E F 2 m- G 2 -2 m- H Part 1) Draw the bending moment diagram of the primary structure and calculate the bending moment at A, D and H. a) M₁ = kN m b) M₂ = c) M₁ = I Part 2) Draw the bending moment diagram of the redundant structure when applying a counter-clockwise unit moment at I. Calculate the bending moment at A, D and H. a) m₁ = kN m b) mp = kN m c) mH = kN m
